E, S, U, Du 5 Information for returning pumps
Equipment which has been contaminated with, or exposed to, body fluids, toxic chemicals or any other substance hazardous to health must be decontaminated before it
is returned to Watson-Marlow or its distributor.
A certificate included at the rear of these operating instructions, or signed statement,
must be attached to the outside of the shipping carton. This certificate is required
even if the pump is unused. See 27 Decontamination certificate.
If the pump has been used, the fluids that have been in contact with the pump and
the cleaning procedure must be specified along with a statement that the equipment
has been decontaminated.
Watson-Marlow 323E, 323S, 323U and 323Du User Manual 6
E, S, U, Du 6 Peristaltic pumps - an overview
Peristaltic pumps are the simplest pump, with no valves, seals or glands to clog or
corrode. The fluid contacts only the bore of a tube, eliminating the risk of the pump
contaminating the fluid, or the fluid contaminating the pump. Peristaltic pumps can
run dry.
How they work
A compressible tube is squeezed between a roller and a track on an arc of a circle,
creating a seal at the point of contact. As the roller advances along the tube, the seal
also advances. After the roller has passed, the tube returns to its original shape, creating a partial vacuum which is filled by fluid drawn from the inlet port.
Before the roller reaches the end of the track, a second roller compresses the tube
at the start of the track, isolating a packet of fluid between the compression points.
As the first roller leaves the track, the second continues to advance, expelling the
packet of fluid through the pump’s discharge port. At the same time, a new partial
vacuum is created behind the second roller into which more fluid is drawn from the
inlet port.
Backflow and siphoning do not occur, and the pump effectively seals the tube when
it is inactive. No valves are needed.
The principle may be demonstrated by squeezing a soft tube between thumb and finger and sliding it along: fluid is expelled from one end of the tube while more is drawn
in at the other.
Animal digestive tracts function in a similar way.
Suitable applications
Peristaltic pumping is ideal for most fluids, including viscous, shear-sensitive, corrosive and abrasive fluids, and those containing suspended solids. They are especially
useful for pumping operations where hygiene is important.
Peristaltic pumps operate on the positive displacement principle. They are particularly
suitable for metering, dosing and dispensing applications. Pumps are easy to install,
simple to operate and inexpensive to maintain.

E, S, U, Du 7 Safety notes
In the interests of safety, this pump and the tubing selected should only be used by
competent, suitably trained personnel after they have read and understood this manual, and considered any hazard involved. If the pump is used in a manner not specified by Watson-Marlow Limited, the protection provided by the pump may be
impaired.
This symbol, used on the pump and in this manual,
means: Caution, refer to accompanying documents.
This symbol, used on the pump and in this manual,
means: Do not allow fingers to contact moving parts.
This symbol, used on the pump and in this manual,
means: Recycle this product under the terms of the EU
Waste Electrical and Electronic Equipment (WEEE) Directive.
Fundamental work with regard to lifting, transportation, installation, starting-up, maintenance
and repair should be performed by qualified personnel only. The unit must be isolated from mains power while
work is being carried out.
Any person who is involved in the installation or periodic maintenance of this equipment should be suitably skilled or instructed and supervised using a safe system of
work. In the UK this person should also be familiar with the Health and Safety at
Work Act 1974.
There is a user-replaceable type T1.0AH 250V fuse
in the fuse drawer of the IEC mains connector at
the back of the pump, which also contains a spare
fuse. In some countries, the mains power plug
contains an additional replaceable fuse. There are no user-serviceable fuses or parts inside this pump.
Watson-Marlow 323E, 323S, 323U and 323Du User Manual 8
There are moving parts inside the pumphead. Before opening the track, ensure that the following safety directions are followed.
Ensure that the pump is isolated from the mains power.
Ensure that there is no pressure in the pipeline.
If a tube failure has occurred, ensure that any fluid in the pumphead has been
allowed to drain to a suitable vessel, container or drain.
Ensure that protective clothing and eye protection are worn if hazardous fluids
are pumped.
Primary operator protection from rotating parts of the pump is provided by the
pumphead track. See 23 Pumpheads.
This product does not comply with the ATEX directive
and must not be used in explosive atmospheres.
This pump must be used only for its intended purpose. The pump must be accessible
at all times to facilitate operation and maintenance. Access points must not be obstructed or blocked. The pump’s mains plug is the disconnecting device (for isolating
the motor drive from the mains supply in an emergency). Do not position the pump
so that it is difficult to disconnect the mains plug. Do not fit any devices to the drive
unit other than those tested and approved by Watson-Marlow. Doing so could lead to
injury to persons or damage to property for which no liability can be accepted.
If hazardous fluids are to be pumped, safety procedures specific to the particular fluid
and application must be put in place to protect against injury to persons.
The exterior surfaces of the pump may get hot during operation. Do not take hold of
the pump while it is running. Let it cool after use before handling it.
No attempt should be made to run the drive without a pumphead fitted.

9.1 General recommendations
Position
A correctly engineered installation will promote long tube life. Site the pump on a
flat, horizontal, rigid surface, free from excessive vibration. Allow a flow of air around
the pump to ensure that heat can be dissipated. Ensure that the temperature around
the pump does not exceed 40C.
Emergency disconnection
The pump’s mains plug is the disconnecting device (for isolating the motor drive from
the mains supply in an emergency). Do not position the pump so that it is
difficult to disconnect the mains plug. The STOP key on the keypad will always stop
the pump. However, it is recommended that a suitable local emergency stop device
is fitted into the mains supply to the pump.
Valves
Peristaltic pumps are self-priming and self-sealing against backflow. No valves are
required in inlet or discharge lines. Valves in the process flow must be opened before
the pump operates. Users are advised to fit a pressure relief device between the pump
and any valve on the discharge side of the pump to protect against damage caused
by accidental operation with the discharge valve closed.
The pump may be set up so that the direction of rotor rotation is clockwise or
counter-clockwise, whichever is convenient.
Tubing materials: run-in advice
Sta-Pure and Marprene tubing are hard to compress when new. When using
tubing made of these materials, the first 30 seconds should be at a speed of 10 rpm
or greater. If the pump is run slower, the safety system built into pump drive’s software may cause it to stop and display an over-current error message.
